ORA-00832: no streams pool created and cannot automatically create one
Cause: A database feature which needs STREAMS SGA was being used, however, the streams_pool_size parameter was not defined and the value of db_cache_size was too small to permit an automatic transfer of SGA to the streams pool from the buffer cache.
Action: Please set the parameter streams_pool_size or set sga_target.

As of Oracle Database 10g release 10.2, if Streams functionality is used, but the STREAMS_POOL_SIZE initialization parameter is not defined, then the size of the streams pool automatically defaults to 10% of size of the shared pool.

When the streams pool is created, the required SGA memory is taken from memory allocated to the buffer cache, reducing the size of the cache to less than what was specified by the DB_CACHE_SIZE initialization parameter. This means that if the buffer cache was configured with only the minimal required SGA, then Data Pump operations may not work properly.
